feat(hintControllers): warn about controller naming conventions

Add warnings for naming controllers with lowercase first letters as
well as without the suffix -Controller.

Closes #2
refactor(hintControllers): use new ngHint configuration
feat(hintControllers): give version specific deprecation warning

Since global controllers are deprecated in 1.3.x, hintControllers
should explain the behavior in 1.3.x rather than warning about
best practices.

Closes #1
